GENERAL DESCRIPTION
The AD8450 is a precision analog front end and controller for
testing and monitoring battery cells. A precision programmable
gain instrumentation amplifier (PGIA) measures the battery
charge/discharge current, and a programmable gain difference
amplifier (PGDA) measures the battery voltage (see Figure 1).
Internal laser trimmed resistor networks set the gains for the
PGIA and the PGDA, optimizing the performance of the
AD8450 over the rated temperature range. PGIA gains are 26,
66, 133, and 200. PGDA gains are 0.2, 0.27, 0.4, and 0.8.
Voltages at the ISET and VSET inputs set the desired constant
current (CC) and constant voltage (CV) values. CC to CV
switching is automatic and transparent to the system.
A TTL logic level input, MODE, selects the charge or discharge
mode (high for charge, low for discharge). An analog output,
VCTRL, interfaces directly with the Analog Devices, Inc.,
ADP1972 PWM controller.
The AD8450 includes resistor programmable overvoltage and
overcurrent detection and current sharing circuitry. Current
sharing is used to balance the output current of multiple
bridged channels.
The AD8450 simplifies designs by providing excellent accuracy,
performance over temperature, flexibility with functionality,
and overall reliability in a space-saving package. The AD8450 is
available in an 80-lead, 14 mm × 14 mm × 1 mm LQFP package
and is rated for an operating temperature of −40°C to +85°C.
